I have changed the filter and fuild and no help

Junkyard time or get a new transmission.

You may have a bad Solenoid in the Valve Body. There should be a 700 series Trouble Code in the PCM if that was the case. But since you didn't tell the mileage, it could just be a worn out tranny that was never serviced until just recently. Check for codes.

Hi so slipping transmissions are due to wear hardly surprising in a car that has lasted twice as long as intended. If it is a manual gear change it is a simple clutch replacement. However as a lot are automatic this becomes a rather expensive repair. So time to be realistic about the modern car and get it fixed.

Time for rebuilt transmission. Find local shop at ATRA.COM for more help

Once an automatic transmission starts to slip it needs rebuilding. You're looking at $1800.

How do i check the codes
